JOHN SGHEIDLER, OF COLDWVATER, MICHIGAN.

SELF-SUPPORTlNG ROOF.

SPECIFICATION forming part of Letters Patent No. 332,115, dated December 8, 1885.

Application filed August 11, 1885. Serial No. 174,147. (No model.)

To all whom it may concern.-

Be it known that I, JOHN SOHEIDLER, a citizen of the United States, residing at Cold water, in the county of Branch and State of Michigan, have invented a new and useful Improvement in Self-Supporting Roofs, of

-which the following is a specification, reference being had to the accompanying drawings.

My invention relates to an improvement in self-supporting roofs; and it consists in the peculiar construction and combination of devices that will be more fully set forth hereinafter, and particularly pointed out in the claims.

In the accompanying drawings, Figure 1 is an elevation ofmy invention, Figs. 2 and 3 are similar views, illustrating modified forms of my invention. Fig. 4 is a detail section of the block.

A represents the rafters of the roof, which have their meeting ends beveled in the usual way to form the angle-joints B. In the angles formed by the meeting ends of the rafters are placed blocks 0, the outer edges of which are preferably curved and provided with grooves D. On the outer sides of the rafters, at the joints thereof, are placed metallic straps E, which extend in opposite directions from thejoints.

F represents substantially U-shaped bolts, the curved portions of which are fitted in the grooves D of the blocks, and the extending arms of which bolts pass through the rafters and through the ends of the metallic straps. On the ends of the arms of the bolts, which are provided with screw-threads, are placed washers G, that bear on the upper sides of the straps, and nuts H are then screwed on the threaded ends of the bolts and clamp the rafters and the blocks tightly together, thus forming absolutely secure joints for the rafters and rendering the roof self-supporting, and dispensing altogether with the usual kingpost.

In the construction of barns or store-houses where a hay-carrier or other similar apparatus is employed, the latter may be suspended directly from the center of the roof by making transverse openings I in the blocks under the central joints for the reception of the suspending hooks or rods.

In Fig. 2 I illustrate a modified form of my invention which may be employed in gableroofs, where extraordinary strength is not required. In this case the block 0 is straight on its under side, and two bolts, F, of the ordinary form, are used instead of the U-shaped bolts F for each joint.

Fig. 3 shows another modification, in which the strap extends for a considerable distance beyond the joint of the rafters, the blocks 0 being correspondingly increased in size.

Having thus described my invention, I claim- 1. The combination, with the jointed rafters, of the straps on the upper sides of the joints, the blocks in the angles formed by the joints, and the bolts securing the blocks, the rafters, and the straps together, substantially as described.

2. The combination of the jointed rafters, the blocks 0 in the angles formed by the joints, said blocks having the grooves D, and the U-shaped bolts having the curved portions in the grooves and the arms extending through the rafters, and the nuts for clamping the blocks to the rafters, substantially as described.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in presence of two witnesses.

JOHN SCHEIDLER.
